Post-quantum cryptography is being standardized at the protocol layer. But your application's cryptographic surface — WebCrypto calls, WASM libraries, key management patterns — remains exposed. QubitBlocker monitors, audits, and scores your domain's quantum readiness in real time.
These aren't theoretical. Adversaries are already collecting encrypted traffic. The application layer is the blind spot.
Adversaries capture your TLS-encrypted traffic today. When quantum computers mature, they factor your RSA or ECC keys and decrypt everything — session tokens, user data, API keys.
Critical — Active NowYour JavaScript calls WebCrypto with RSA-OAEP. Your WASM module uses secp256k1. Your key derivation uses PBKDF2 with insufficient iterations. All quantum-vulnerable, all client-side.
Critical — Active NowAs quantum capabilities emerge, adversaries test them against live targets. The behavioral signature differs from classical attacks — distinct timing, unusual failure modes.
High — EmergingLong-lived certificates and static API keys amplify harvest-now risk. If your TLS private key hasn't rotated in 6 months, every session it protected is potentially compromised.
High — Active NowCDN scripts, analytics embeds, and SSO widgets all establish their own crypto contexts. A single third-party script using SHA-1 creates a quantum-vulnerable entry point.
Emerging — UnderservedNIST published final PQC standards (FIPS 203, 204, 205) in August 2024. If your application can't consume PQC ciphersuites when the server offers them, you're exposed.
Emerging — Time-SensitiveFive detection layers operating continuously at the application boundary. No server changes required.
Inspects the active TLS connection's cipher suite and key exchange method. Reports whether PQC hybrid modes are active.
Intercepts WebCrypto and SubtleCrypto calls at runtime. Enumerates every algorithm, key size, and hash function. Flags quantum-vulnerable primitives.
Detects WebAssembly modules that implement cryptographic operations outside the browser's native APIs by monitoring compilation calls.
Combines TLS parameters, certificate age, key rotation frequency, crypto surface exposure into a 0–100 risk score.
Monitors cryptographic operation timing for patterns consistent with quantum-accelerated probing.
Maps every script origin and checks each one's TLS parameters. Flags third-party resources that downgrade quantum security posture.
Live visualization of the detection pipeline. Toggle monitoring to observe how quantum-vulnerable crypto operations are flagged.
QubitBlocker initializes synchronously before any application code runs. It intercepts WebCrypto, audits TLS, and begins monitoring — zero configuration required.

On load, QubitBlocker inspects TLS, intercepts WebCrypto, scans for WASM crypto modules. No initialization needed.
Scan results appear in your dashboard with risk scores, vulnerability breakdowns, and historical trends.
The threat isn't hypothetical. The timeline is already in motion.
Peter Shor proves that a quantum computer can factor integers in polynomial time, theoretically breaking RSA and ECC.
NIST launches a formal process to evaluate and standardize post-quantum cryptographic algorithms. 82 initial submissions.
NSA and GCHQ publicly warn that nation-state adversaries are actively recording encrypted traffic for future quantum decryption.
FIPS 203 (ML-KEM), FIPS 204 (ML-DSA), FIPS 205 (SLH-DSA) published. Federal agencies receive migration mandates.
Servers begin supporting PQC ciphersuites, but client-side applications remain unprotected. QubitBlocker addresses this gap.
Major programs projected to reach 4,000+ logical qubits — the threshold for breaking RSA-2048. Harvested traffic becomes decryptable.
